In Hawaii, the friendly shaka sign — with thumb and pinkie extended and middle fingers curled down — means any number of things, from hello to hang loose. When clients check in at Aqua Hospitality, the shaka sign will earn them an additional 10 percent savings on the property’s best available rate.

“The shaka is a unique local custom,” said Elizabeth Churchill, Aqua’s senior vice president of sales and marketing. “It’s a fun way to interact with our guests and celebrate our Hawaii roots.”

Good on stays through Dec. 31, the deal applies to new reservations at participating Aqua Hospitality properties around Hawaii. www.aquahospitality.com
